Community-Wide Emissions Reduced 44 per cent from 1990 Levels

The City’s 2017 inventory on community-wide greenhouse gas (GHG) emissions – which measures the emissions from energy use in buildings, vehicles, waste and industry – indicates that GHG emissions in Toronto were 44 per cent lower in 2017 than in 1990.

Key findings:

Emissions from all sectors continue to go down, even in the context of economic and population growth.

 

  • 52 per cent of GHG emissions in Toronto comes from homes and buildings, primarily from burning natural gas to heat indoor spaces and water
  • 38 per cent of GHG emissions in Toronto are generated by transportation, with 80 per cent generated by personal vehicles
  • 10 per cent of GHG emissions in Toronto are generated by waste

Reporting annually is part of the City’s commitment to address climate change and inform the development of its climate strategy and policy.
